. panying drawin s, forming part of this specification, in WhlC Figure 1 is a plan view and Fig. 2 is a sectional elevation on the line IIII of Fig. 1, showing our improved apparatus. Fig. 3 is a horizontal sectional view on the line IIIIII of Fig.2 and Fig. 4 is a detail view showing one form of the vessel holdin mechanism.

In many of the various anaflytical methods practiced in chemical laboratories, when dissolving or precipitatingonesubstance inv another such as a solid in a liquid, a necessary step in such methods is to frequently agitate the solutions by shaking the containing ves- Heretofore this has been plished by manual labor, the attendant successively shaking the vessels until the chemical reaction is completed, the shaking operation requiring the entire attention of the attendant.

Our invention is designedfor use in such laboratories and the ObJGGt of the invention is to provide improved mechanism by which these shaking operations are performed by mechanical means, without requiring the attention of the attendant, thereby facilitating and reducing the cost of such operations.

In the drawings, 2 represents a bent shaft having a straight lower portion which is rotatably mounted the vertical bearings 3, 4 on the tripod or base 5 of the apparatus. A hardened steel plug 6 is adjustably secured in the lower end of the bearing 3 to support v and take the end thrust u on the lower end" of the shaft. Secured to th a point midwa between the bearings 3, 4 is dirivin e bent shaft 2, at

a pulley 7 for the a paratus, the pullei being positively riven by means of a belt w ich is connected to any desired type of motor.

The upper portion of the bent shaft2 is provided witha loose table bearing 8 having a circular flange or disk portion 9 to which the table or disk 10 is secured; by means of tap bolts 11 or otherwise as desired, The

upper end of the table-bearing 8 is provided table-bearing table, however, moves through a curved or with an adjustable bearing plug .12 which contacts with the upper end of the bent shaft 2 and supports the Weight of the apparatus carried by the table-bearing 8. For lubricating the table-bearin opening 13 in the end of t he plug 12. The

we provide the upper end of the bearing 4 is provided with] a series of teeth 14 which mesh with a similar series of teeth 15 on the lower end of the table bearing 8 and serve to prevent the table bearing 8 and table 10 from rotating when the power driven pulley 7.

' Mounted on the table 10 is a series of nests having sets of upwardly and outwardly extending fingers 16 which engage with and re-- tain the base portions of the vessels containing the solutions to be agitated or shaken, in position on the table. Above each set of fin ers 16 is a sprin clamp 17 which ispreferaflaly made vertica ly adjustable, as shown. The clamp 17 is secured to the squared post 18, the post 18 being mounted in the vertical hollow guide 19 which is rigidly securedin lace on the table 10. The upper end of the ollow guide 19 is closed, a suitable opening being provided in the end of the guide for the squared post 18. The lower en of the post 18 is provided with a flange 18 and a helical spring 20 is interposed between this flange 18 of the post 18 and the closed upper end of the hollow guide 19 so as to permit the spring clamp 17 and post 18 to be moved vertically.

. 05 the shaft 2 is revolved in its bearings 3, 4 by" To'retain the table in place on the bent shaft and prevent its being lifted from the shaft 2 a set-screw 21 is provided in the table-bearing 8 which extends through the, side of this bearin into the groove=22 in the bent shaft 2.

In tide operation of the apparatus, the attendant places the vessels containing the solutions to. be shaken on the table 10, the base portions of the vessels being retained in place by the fingers .16 and the upper end of the vessels being held by the vertically adjustable clamp 17 The motor is thenstarted and the bent shaft 2 isjcaused to rotate in its bearings 3, 4. It will be noted that while the shaft 2 is rotated, the table 10 does not revolve, rotation being prevented by the engaging teeth 14, 15 on the inner ends'of the 8 and shaft-bearing 4. The

and rocks or tilts during such movement.

to the contents of the flasks best suited to assist in the dissolution of'the materials in the flasks, without danger of spilling.

The advantages of our invention will be apparent to those skilled in the art to which it is ap lied. By its use the shaking or agitating the solutions contained in the vessels is easily and quickly accomplished without re- .quiring attention of the operator. The apparatus is simple and easily kept in repair.

The spring clamps 17 may be rigidly secured to the table 10 instead of being made vertically adjustable as shown. The number of vessels mounted on the apparatus may be varied and other modifications in the construction and arrangement of the parts may be made without, departing from our invention.
